How do I write this problem?

to receive a grade B- in a math course, you must have a mean of 83 on five tests (4 tests + one final) all 100 pts maximum each. Your scores thus far are 85,79,82,and 81. How many points must you have on the final, to earn the B-? write down your work..

0.83 * 500 = 415

You need a total of 415 points.

Your test grades so far = 327

415 = 327 = 88

You need at least a score of 88 on the final.

You're welcome.

I just noticed that I have a typo:

415 - 327 = 88
